Definitely! I agree.

 

although doors are opening at 8am this morning, the live stream will not begin until closer to 9am.

 

I know we didn't get any close ups of the electronics wiring going in, but if there is anything that you want to see or need to ask, please do so. The wiring still needs cleaned up and I have an updated enclosure to help with this. Aslo, we only toyed with the GRBL panel software and G-code creating (using Fusion 360) for a little bit and don't have any video of that yet. We can put together more as we learn, if you like. Thanks for watching!!

 

It was a sight to behold this year. Almost endless masses walking by the table. I wished we would have panned the camera out into the crowd for perspective. Even Friday evening was busy and that wasn't technically open to the public yet. We had so many people tell us their stories, a few concerns, and some new ideas to pass along. I'll send a summary email, detailing everything I can remember.

 

Notice the origin location in my marked up drawing. When you press "right arrow" key the X axis will increment in the positive direction for tool output (which is actually moving the gantry to the right). "Page Up" should move the tool up, away from the table surface. When you press the "up arrow" key the Y axis will increment in the positive direction for tool output (which is actually moving the Y table toward the front of the machine, since the X-Z gantry can't move away from you). This gives you positive tool output as expected and is correct.
In your image, the X-Z gantry is able to move in the Y direction, instead of the table moving in the Y. If you were build a machine with this kinematics, your Y wires would need to be reversed from mine. The C-beam machine has a disconnected, independent Y-axis so it's movement, relative to X-Z, is reversed when compared to the kinematic system your picture shows.

I hope that helps.

 

We aren't sure what all this machine will be doing yet. I would like to add a full enclosure guard (one that just sits down over the entire machine) with sight windows and make it a laser cutter, but it is mainly going to be used to engrave and mill - probably aluminum plates per its name and engrave small signs. Either way, it will be most handy.

 

I haven't tried the OB samples, so I don't know if they work properly. I would say if you are jogging correctly, you are probably setup properly.
